Found out today my spa gauges are not compatable with the signal sent out by the ecu on my LS7 so going to have to use the sensors that came with the gauges. Oil pressure and water temp. Going to put water temp on heater outlet from block, is that the one nearest to the rear bulkhead of the car? Anyone know where the oil pressure sensor is on the ls7 as I am hoping to put in a T piece.

Hi Adam,

How did you find this out old chap?
I am in a similar position. Got the SPA Dash and two separate digital guages.

I am in the middle of running all the wiring + oil lines+ engine fit!
Will be interesting to watch this thread!

cheers

Keith

Found out when I connected them up as instructed by Mast who supplied the engine and ECU and they didn't work!
ECU puts out resistance or duty, but Spa use a voltage feed. Managed to run the rev counter (spa dash) from the ECU feed.
Still trying to work out how to set the petrol gauge up on the dash!

Stick a meter on the output from the ECU and see what you got
